Abstract

A modular electric axle head assembly for a vehicle, including a gear assembly including a gear assembly housing defining a hollow portion therein, a first gear shaft having a first gear, a second gear shaft having a second gear and a third gear, wherein at least a portion of the second gear is drivingly connected to the first gear and the third gear, and at least a portion of the gear assembly is disposed within the hollow portion of the gear assembly housing; a motor assembly having an output shaft that is drivingly connected to at least a portion of the gear assembly; and a first mounting assembly including a portion integrally connected to the modular electric head assembly and a portion integrally connected to a support member of the vehicle, wherein at least a portion of the third gear is drivingly connected to a pair of drive shafts.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit to U.S. Provisional Patent Application No. 62 / 554,156 filed on Nov. 10, 2017, which is incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to a modular electric axle head assembly for use in an electric vehicle and / or a hybrid electric vehicle.BACKGROUND[0003]In recent years' considerable attention has been given to producing vehicles with increased fuel efficiency to reduce the overall fuel consumption of motorized vehicles all over the world. Additionally, in light of increasingly stringent emission controls considerable attention has been given to producing vehicles that produce fewer emissions. As a result, considerable attention is being given to producing hybrid vehicles and all electric vehicles that have a reduced fuel consumption and produce fewer emissions. Hybrid vehicles typically use two or more distinct power sources to provid...
